Sounds almost like it has or had air in it.

I agree with Craigy2; it does sound like you have air in the drive/drive control circuit. The pop could be burping air in.

Getting stronger with use certainly sounds like flushing air from the motor circuit.

I can think of two main ways to get air in

1. Could you have gotten air in during a filter change?
2. Could there be a loose connection anywhere on the vaccum side of the intake to the tram pump?

All the best,

Peter
